Incorrect Billing

On the 9 April 2015 I cancelled my data contract with Cell C and opended two new contracts. I confirmed that end April will be my last payment for the data contract. On the 31 May 2015 they withdrew the data contract's money from my account in error. I contacted the call centre got a reference number ***) and send 2 e-mails and still no feedback. I requested them to refund the extra money taken off my account in error and to get confirmation that it will not happen again. Up to now no feedback yet. This after they phoned me about 6 times during May to find out why I cancelled the contract. This is just bad service and will make me think twice when I have to renew my remaining contracts with them. <br>
